Library Rotunda Home Office, Washington, D.C.

The home writing studio of National Geographic Explorer-in-Residence, anthropologist, photographer, ethnographer and author Wade Davis, sits under a 16-foot dome containing the library of books he uses the most, accessible only via a ladder. Travis Price, the architect, said it is reminiscent of the round Greek temple or Tholos at Delphi. The space is connected to the explorer’s otherwise traditional turn-of-the-century Four Square-style home via a glass greenhouse.
